If you fast forward to the part in King Louie's ruins in the middle of the song. When he's skipping jump rope with his arms, listen and you can hear him sputtering jibberish that sounds a whole lot like he's saying Chewbacca, a wookie from the "Star Wars" series. It's ironic because they're both covered in hair.
That's not ironic. The word you're looking for it coincidental. For what it's worth, I don't think the man who came up with the name Luke Skywalker is original enough to have come up with the name Chewbacca on his own. I'd give the credit for Chewbacca's name to Louis Prima. If it's not the truth, it's the best theory I've heard yet.
